Thermal management is a major challenge for new generation turbofan aero-engines. One of the most promising heat exchangers are so-called surface air-cooled oil coolers (SACOCs). In this study, an experimental methodology proposed and implemented in order to characterize SACOCs mounted bypass ducts. Three different SACOC geometries have been characterized under same nominal operating point, whi...

Alternative fuels containing biocomponents produced in various technologies are introduced aviation to reduce its carbon footprint but there is little data describing their impact on the performance and emissions of engines. The purpose work compare gas from two different jet engines—the GTM-140 microturbine full-size DGEN380 turbofan, powered by blends Jet A-1 one biocomponents: (1) Alcohol-to...
